Strange transmissions have been heard on the Frequency 4625 kHz.
Listen to it here.
Currently there is only a monotonous Buzz.
Keep trying you may find something.
“Also known as The Buzzer, this shortwave radio station has existed since the late 1970s, usually broadcasting nothing more than a repeating buzz tone. But sometimes, like last night, that tone is interrupted, replaced with a mysterious voice transmission.”
At 2225 UTC on September 1, 2010, the buzzer was interrupted by a 38-second fragment of “Dance of the Little Swans” from Tchaikovsky’s ballet Swan Lake. Four days later on September 5 at 1230 UTC, a female voice was heard counting from one to nine in Russian; just over an hour later, at 1339 UTC, the buzzing silenced for a quiet male voice to read a voice message.”(wiki)…
To listen to other recent UVB-76 voice transmissions, they’ve been logged over at Priyom.org. There’s definitely something creepy about those messages…
